ubuntu 10.10 crashes with memory > 4G (out of hypervisor heap guru) -> fixed in SVN

Description

Hello experts,

i run ubuntu 10.10-64 (desktop) as guest on a Win7-64 (Mem: 12GB) Host

The guest can be started, but after login (when starting the user session) the system crashes, but only when main memory is more than 4G. Worked fine with VB 3.2.8!

the ubuntu guest system crashes, not the host! sorry!

You can work around it by changing an internal config value:

VBoxManage setextradata "VM name" "VBoxInternal/PGM/Pool/MaxPhysExts" 2048

If that doesn't help, then please upload another log file (so I can check you did it correctly).

Hello sandervl73,

setting the extradata did not help. I send you the logfile.

I will try out the testbuild.

Thanks!

regards

hello sandervl73,

the testbuild also does not work with mem >4G :-(( I attach the new log.

But i recognized a difference between startup with <=4G and > 4G:

When starting up with more than 4G there is an info in the window that does not appear when starting with <= 4G:

modprobe: FATAL could not load /lib/modules/2.6.35-22 generic/modules.dep No such file or directory

Googleing around i found some tips but no working solution.

regards

Well, you still get a Guru Meditation.

comment:8 by Sander van Leeuwen, 14 years ago

Could you try this build?

comment:9 by tommy, 14 years ago

with this build (r66734) it is not possible to start at all. A messagebox appears: "VirtualBox GUI funktioniert nicht mehr" (in english: Virtualbox GUI does not work anymore)

one more log attached ;-)

i have to correct me: the client starts up with memory up to 3575MB.

comment:11 by Frank Mehnert, 14 years ago

Please test this build, the VM should now start with more than 3575MB RAM.

comment:12 by tommy, 14 years ago

This build (66799) works fine now with more than 4G! (though the modprobe error is still appearing) and i can start my application that needs a lot of main memory without problems.

thanx for your help!

Regarding the modprobe error: Did do depmod -a in your guest?

Replying to frank:

Regarding the modprobe error: Did do depmod -a in your guest?

sorry for my late answer:

Restarting after running 'depmod -a' did not show the message. But after a next restart it is shown again.

tommy, in that case make sure that you rebuild the initram disk. Do

depmod -a
update-initramfs -c -k $(uname -r)
